Benefits and constraints on toolbar and menu precaching

When a toolbar or object menu cannot be found in the client cache, the client has to make an AppServer request to retrieve the necessary information. Caching multiple toolbars at session startup results in fewer AppServer requests given that each toolbar cached in the initial request would otherwise have required a later request.

As with any caching at session startup, caching toolbars and container menus at session startup requires a longer Dynamics startup time. An extra AppServer request is also made when the session starts. It is also possible that toolbars and menus cached at session startup might not be used in the session, in which case the caching overhead incurred at startup has been unnecessary.
